Hey guys is 175-200F really the normal operating temps of these transmissions? I've had a Bully Dog in mine since before I got Nissan to replace my Tranny at 92K and am 55k into this one. I was really used to seeing the transmission run at 150F until maybe the last 20k it seems to range between 162-182F which I was starting to get concerned about. I had a flush 2K ago with no change in performance... I have bunch more data to vom out but lets see what you kind folks have to say.smj999smj wrote:If it were not for the factory installed, auxiliary trans cooler, the radiator's integral cooler would probably be doing more of the job of actually cooling the oil. Since, the auxiliary cooler takes care of the cooling of the fluid, the radiator's integral cooler serves as an additional cooler if and when it is ever needed, as well as a device to maintain the temperature of the fluid in the 175-200 degree F. range, the temperature range that the transmission oil should be operating within.
I believe those that were monitoring the trans temps were using a Bully Dog, possibly with an additional temp sensor. Hopefully one of them will chime in with what they used.
2010 is the last year included in Nissans' customer satisfaction/extended warranty campaignAjahn wrote:Bump. I have the same concerns as Sanfer. Recently purchased a 2012 pathfinder, 45k on it, do I need to be concerned about this? Living in cold weather, the bypass would not be an option. I would assume adjustments have been made since 2005/06 to correct the seals with the radiator manufacture but am looking for verification.
